Ooii Files Renamer

Ooii Files Renamer is an intuitive piece of kit you can use to rename multiple files in bulk by specifying a set of rules. It's practical for those looking to reorganize personal documents, pictures, videos, and anything else of importance.

Requirements and interface

The program's not packed in a setup kit. Instead, it consists of a single .exe file that you can save anywhere on the disk or copy to a removable storage unit, in order to seamlessly launch it on any computer with little effort.
It doesn't integrate new entries into the system registry or create files on the disk without letting you know about it. On the other hand, it was developed with .NET Framework, so you must have this platform installed.
Regarding the interface, Ooii Files Renamer opts for a simple look and structure, preferring to focus on delivering straightforward task. It's possible to populate the task list with as many files as you want to rename, as well as to view their current name and full path. Any entry can be removed from the queue if you change your mind.

Create rules to rename a batch of files

There are multiple file renaming methods put at your disposal, so you can take your time to explore each one. For instance, you can remove part of the name or replace it with something else, add a prefix or suffix using time, date or numbers, as well as add a suffix right before the file's extension instead of at the end of it.
Furthermore, you can insert a custom string of characters at any position in the file name, before or after another string of characters, delete the current name before adding a new one, as well as convert the text to uppercase, lowercase or capitalization. It's also possible to manually rename each file by clicking on their cells to edit content, just like using a common word processor.
All modifications are applicable with the click of a button. Once the operation is over, Ooii Files Renamer gives you the possibility to undo changes if you're not pleased with the outcome.
